Abstract
The invention discloses a processing method of green corns precooked with cases and hulling deepfreezing, comprising the steps in turn: collecting, precooling, precooking, cooling, hulling, grading, deepfreezing, clothing the thin ice, boxing, chilling and the like. The invention can effectively preserve original color, taste of the fresh corns, has abundant nourishment and high health care values.
Description
Technical field:
The present invention relates to a kind of fresh-keeping and preserving method of sapphire rice.
Background technology:
During existing sapphire rice fresh-retaining preserving is handled, the method complexity, not really desirable at aspects such as the original color and luster that keeps new fresh waxy corn, local flavor, nutritional labelings, precook when handling, shell is peelled off.
Summary of the invention:
The object of the present invention is to provide a kind of blue or green corn belt shell that can effectively keep the original color and luster of new fresh waxy corn, local flavor processing method for quick-freezing of precooking, shell.
Technical solution of the present invention is:
Shell processing method for quick-freezing of precooking, shell in a kind of blue or green corn belt is characterized in that: comprise the following steps: successively
(1) gather: in corn pollination the last 20～25 days, the blue or green waxy corn fringe of gathering was gathered and is carried out in morning, stopped to gather after at 7 in the morning, when gathering, blue or green waxy corn fringe was broken off with the fingers and thumb down, cut except that fruit ear root and fringe palpus;
(2) precooling: with blue or green waxy corn fringe 5～15 ℃ of following precoolings;
(3) precook: blue or green waxy corn braid shell is put into the pot water that boils precooked 10～25 minutes;
(4) cooling: the blue or green waxy corn fringe after will precooking is cooled to central temperature below 10 ℃;
(5) peel off, classification: divest blue or green waxy corn fringe bud shell, and carry out classification by size;
(6) quick-frozen: blue or green waxy corn fringe is freezed under-30～-35 ℃, blue or green waxy corn fringe central temperature is reached below-18 ℃;
(7) hang the ice clothing: will hang the ice clothing through the blue or green waxy corn fringe that quick-frozen is handled and handle;
(8) vanning: the blue or green waxy corn fringe behind the extension ice clothing is cased, is sealed;
(9) refrigeration: the blue or green waxy corn fringe after will casing is put into-20～-25 ℃ freezer and is refrigerated, and in the cold storage procedure, temperature fluctuation range is no more than 1 ℃, relative humidity 95%～100%, and in the cold storage procedure, the relative humidity fluctuation range is no more than 5%.
Pollinated back 23 days the blue or green waxy corn fringe of gathering at corn.
The quick-frozen processing time is 5～15 minutes.
The method of hanging the processing of ice clothing is: the blue or green waxy corn fringe of at every turn getting 2～4 kilograms is put into basketry, immersed in 1～3 ℃ of sterile-processed cold water 2～3 seconds, and leave the water immediately after shaking basket once rapidly, draining, this moment, the outer surface of blue or green waxy corn fringe formed layer of transparent ice clothing.
The present invention can effectively keep the original color and luster of new fresh waxy corn, local flavor, and is nutritious, and health care is worth high.Particularly when precooking, the band shell is precooked, and can more can keep the original color and luster of new fresh waxy corn, local flavor and healthy nutritive value than the processing of shelling, and the back generation mechanical damage of can avoiding shelling, and influences product appearance.Handle by hanging the ice clothing, can prevent from corncob drying loss and oxidation stain in cold storage procedure of freezing to guarantee blue or green waxy corn fringe good surface appearance color and luster, help extending the shelf life.
The invention will be further described below in conjunction with embodiment.
The specific embodiment:
